National Mammography Database for Breast Cancer Screening and Diagnosis in Females Aged 2 to 99 Years

What this Trial Is About

This observational study collects mammography data from women to help radiology practices compare their performance with national and regional benchmarks. It focuses on breast cancer screening and diagnosis by using data that facilities are already required to gather under federal rules. The American College of Radiology leads this effort to improve breast imaging quality through shared information. Participants include all women undergoing mammograms, with no specific treatments or interventions applied. The study provides semi-annual feedback reports to Breast Imaging Center of Excellence facilities, showing important benchmarks like cancer detection rates, positive predictive values, and recall rates. Participation is free for these qualified centers. Women in the study have their mammogram data collected and analyzed regularly. The main outcome measured is the cancer detection rate over one year. This monitoring helps facilities understand and improve their screening quality. The study began in 2009 and continues through 2026, with ongoing data collection and reporting throughout this period.
